Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to printing apparatuses, and
more particularly to a printing apparatus with a paper out
mechanism.
[0003] 2. Description of Related Art
[0004] A printing apparatus may include a printing body and a paper
tray secured to the printing body. The paper tray is configured to
receive a printed paper from the printing body and stretchable to
receive different size of printed papers. When the printing
apparatus needs to print different size of papers, it is very
inconvenient to manually stretch or retract the paper tray to
satisfy the size of the papers every time. Therefore, there is room
in the art for improvement.

DETAILED DESCRIPTION
[0014] The disclosure is illustrated by way of example and not by
way of limitation in the figures of the accompanying drawings in
which like references indicate similar elements. It should be noted
that references to "an" or "one" embodiment in this disclosure are
not necessarily to the same embodiment, and such references mean at
least one.
[0015] FIGS. 1-2 illustrate a printing apparatus in accordance with
an embodiment. The printing apparatus includes a printing body 10
and a paper out mechanism 300.
[0016] The printing body 10 defines a paper out opening 11. Two
mounting boards 13 are located on two opposite sides of the paper
out opening 11. The two mounting boards 13 are secured to the
printing body 10 via a common fixed mode, such as, a screw locking
mode and a buckling mode.
[0017] The paper out mechanism 300 includes a support base 20, a
paper out tray assembly 30 secured to the support base 20, and an
actuating device 60. FIG. 4 shows that the actuating device 60
includes an actuating structure 40 and a driving gear 50. The paper
out tray assembly 30 is capable of receiving different size of a
first paper 70 (shown in FIG. 6) and a second paper 80 (shown in
FIG. 8). A size of the first paper 70 is smaller than a size of the
second paper 80.
[0018] The paper out tray assembly 30 includes a paper tray 31 and
a holding tray 33 slidably secured to the paper tray 31.
[0019] The paper tray 31 includes an installation portion 311
secured to the support base 20 and a bearing board 313 secured to
the installation portion 311. In one embodiment, the installation
portion 311 is a box. A sliding rail 3110 is defined in one side of
the installation portion 311, and a sensor 3112 is fixed on one end
of the sliding rail 3110. Two stopping posts 3131 and an
installation post 3133 protrude from an inner side of the bearing
board 313. The two stopping posts 3131 are engaged with a locking
member 90 to secure the actuating structure 40 to the bearing board
313. The locking member 90 defines two locking holes 91 for
receiving the two stopping posts 3131. In one embodiment, the
installation portion 311 directly defines two receiving holes for
receiving the two stopping posts 3131. A controller 3135 (shown in
FIG. 3) is mounted on one side of the bearing board 313.
[0020] FIGS. 4 and 5 show that two sliding posts 330 are located on
one side of the holding tray 33 and slidably received in the
sliding rail 3110. A blocking member 331 is located on an end of
the holding tray 33 and configured to prevent the first paper 70
and the second paper 80 from sliding out of the paper out tray
assembly 30. The holding tray 33 defines a receiving slot 332
facing the paper tray 31 for receiving the actuating structure 40.
In one embodiment, the receiving slot is substantially U-shaped. A
plurality of teeth 3321 are formed on one edge of the receiving
slot 332.
[0021] The actuating structure 40 is installed on the bearing board
313 and includes a drive 41 and a worm 43 connected to the drive
41. The drive 41 rotates the worm 43. In one embodiment, the drive
41 is a motor. The controller 3135 is electrically connected to the
drive 41 via a first cable 100 and connected to the sensor 3112 via
a second cable 200. The controller 3135 is capable of detecting if
there is printed paper outputted from the paper out opening 11 and
determines the size of the printed paper, then starts the drive 41
working. The sensor 3112 detects outputted length of the holding
tray 33 relative to the paper tray 31 and transfers signals to the
controller 3135. The controller 3135 stops the drive 41 from
working.
[0022] The driving gear 50 is attached to the bearing board 313 and
includes a first gear 51 and a second gear 53 having a same
rotation axis as the first gear 51. The first gear 51 is meshed
with the worm 43. The second gear 53 is meshed with the plurality
of teeth 3321 of the holding tray 33. The first gear 51 has a first
addendum circle, and the second gear 53 has a second addendum
circle. In one embodiment, the first addendum circle is greater
than the second addendum circle. The driving gear 50 defines a
positioning hole 55 extending through the first gear 51 and the
second gear 53.
[0023] FIG. 7 shows that in assembly, the two stopping posts 3131
are respectively inserted into the two locking holes 91 of the
locking member 90. The installation post 3133 is received in the
positioning hole 55 to secure the actuating structure 40 to the
bearing board 313. The bearing board 313 is secured to the
installation portion 311 via a common fastening method, such as a
screw locking, a buckling mode for example. The support base 20 is
secured to the two mounting boards 13. The holding tray 33 is
slidable relative to the paper tray 31 between a first position,
where the holding tray 33 is received between the installation
portion 311 and the bearing board 313 and the blocking member 331
abuts against the bearing board 313, and a second position, where
the holding tray 33 extends out of the paper tray 31.
[0024] FIGS. 6-8 show that when the first paper 70 is outputted
through the paper out opening 11, the controller 3135 receives a
first size of the first paper 70 via a transmitter disposed in the
printing body 10. The controller 3135 controls the drive 41 not to
work, and the holding tray 33 is located in the first position. The
bearing board 313 holds the first paper 70.
[0025] When the first paper 70 is replaced by the second paper 80
and the second paper 80 is outputted through the paper out opening
11, the controller 3135 gets a second size of the second paper 80
via the transmitter. The controller 3135 sends a first signal to
the drive 41, then the drive 41 starts to work and drives the worm
43 to rotate. The rotation of the worm 43 drives the driving gear
50 to rotate, and the driving gear 50 drives the holding tray 33 to
move out relative to the paper tray 31. When the holding tray 33
slides to the second position, the sensor 3112 sends a second
signal to the controller 3135. The controller 3135 receives the
second signal and sends the second signal to the drive 41. The
drive 41 stops working. The holding tray 33 and the bearing board
313 cooperatively hold the second paper 80.
[0026] When the second paper 80 is replaced by the first paper 70
and the first paper 70 is outputted through the paper out opening
11, the controller 3135 receives the first size of the first paper
70 via the transmitter and sends the first signal to the drive 41.
The drive 41 starts to work and rotates the worm 43. The rotation
of the worm 43 rotates the driving gear 50. The driving gear 50
retracts the holding tray 33 relative to the paper tray 31. When
the holding tray 33 slides to the first position, the sensor 3112
sends the second signal to the controller 3135. The controller 3135
receives the second signal and sends the second signal to the drive
41. The drive 41 stops working. The bearing board 313 holds the
second paper 80.
[0027] It is to be understood, however, that even though numerous
characteristics and advantages have been set forth in the foregoing
description of embodiments, together with details of the structures
and functions of the embodiments, the disclosure is illustrative
only and changes may be made in detail, especially in matters of
shape, size, and arrangement of parts within the principles of the
disclosure to the full extent indicated by the broad general
meaning of the terms in which the appended claims are
expressed.
